Output goes to Standard Output. +.PP +The input must be 320 pixels wide by 200 pixels high. If you have an +image of a different size, you can use \fBpamcut\fP or \fBpamscale\fP +to force it to these dimensions. + + +.UN options +.SH OPTIONS +.PP +In addition to the options common to all programs based on libnetpbm +(most notably \fB-quiet\fP, see +.UR index.html#commonoptions + Common Options +.UE +\&), \fBppmtospu\fP recognizes the following +command line options: + + +.TP +\fB-d0\fP +The program does no dithering. + +.TP +\fB-d2\fP +The program uses a 2x2 ordered dither. +.sp +This is the default. + +.TP +\fB-d4\fP +The program uses a 4x4 ordered dither. + + + + +.UN seealso +.SH SEE ALSO +.BR "sputoppm" (1)\c +\&, +.BR "spctoppm" (1)\c +\&, +.BR "pamscale" (1)\c +\&, +.BR "pamcut" (1)\c +\&, +.BR "ppm" (1)\c +\& + + +.UN author +.SH AUTHOR + +Copyright (C) 1990 by Steve Belczyk + + +.UN history +.SH HISTORY +.PP +This program was new in Netpbm 10.58 (March 2012). +.PP +But it was written in 1990. Steve Belczyk posted it along +with \fBsputoppm\fP, \fBspctoppm\fP, \fBpi1toppm\fP, and +\fBpi1toppm\fP - all programs for dealing with Atari image formats - +to comp.sources.misc on July 15, 1990. For reasons that have been lost +to history, all of these entered the Netpbm (then Pbmplus) distribution +\fIexcept\fP \fBppmtospu\fP. +.PP +Georges Kesseler wondered In March 2012 why there was no counterpart to +\fBsputoppm\fP in Netpbm and searched the web, finding only one reference +to \fBppmtopsu\fP: the 1990 comp.sources.misc posting, including the source +code. He emailed the Netpbm maintainer suggesting it be added. +.PP +Bryan Henderson found the source code to be extremely primitive, not even +using common library code. So Bryan completely recoded it, but retained +nearly all of the original logic. +.SH DOCUMENT SOURCE +This manual page was generated by the Netpbm tool 'makeman' from HTML +source.
